What would help you and actually almost everyone, is to find a dietologist with solid background in biochemistry. He/she should guide you through a series of tests, blood, dna, metabolism function measurements and then he/she could tell you exactly what would be good and effective for you and what not. In a good medical center probably they can do that as well. The key is the measumerements of your metabolism as you take each supplement to see how the body reacts and/or accepts which supplement, how much it is absorbed, why, under what circumnstances.
